Seagate 9W4001-401 120GB IDE Ultra ATA/100 7200 3.5-inch 2MB Hard Drive

Product Description

The Seagate 9W4001-401 is a 3.5-inch internal hard drive with a substantial 120 GB storage capacity. It utilizes the IDE (Integrated Drive Electronics), also known as PATA (Parallel ATA), interface, supporting the Ultra ATA/100 standard. This standard allows for data transfer rates of up to 100 MB/s, providing respectable performance for its interface type. The drive operates at a spindle speed of 7200 RPM, which contributes to faster data access times compared to slower 5400 RPM drives. Equipped with a 2 MB cache buffer, this hard drive helps to improve performance by temporarily storing frequently accessed data, reducing the need to access the slower platters. The 7200 RPM rotation speed ensures that the read/write heads can quickly locate data sectors on the spinning platters. This combination of speed and cache makes it suitable for use as a primary boot drive or a secondary storage drive in desktop computer systems from the era when IDE was prevalent. This particular model, identified by SKU 9W4001-401, was a common choice for system builders and users looking for reliable storage solutions. While IDE interfaces have largely been superseded by SATA, drives like this were instrumental in the evolution of personal computing storage. It represents a solid-state storage solution from a time when mechanical hard drives were the standard for capacity and affordability.
